'Quench' in the Bible

And, behold, the whole family is risen against thy handmaid, and they say, Deliver him that smote his brother, that we may kill him for the life of his brother whom he slew, and so destroy the heir also. Thus will they quench my coal which is left, and will leave to my husband neither name nor remainder upon the face of the earth.

But Abishai the son of Zeruiah succored him, and smote the Philistine, and killed him. Then the men of David sware unto him, saying, Thou shalt go no more out with us to battle, that thou quench not the lamp of Israel.
